In the current study, the hypothesis was explored that the difference in leaf OP between the two lines was associated with differences in transpiration rate which in turn had a major effect on the temporal dynamics of soil water use. The line with the lowest (most negative) OP in the early stages of the soil drying cycle was found to have the greatest transpiration rate and delayed wilting which was consistent with the original field observations. However, with further soil drying, the line with higher OP was able to sustain transpiration over a longer time period and actually reached the end point of transpirable soil water at a later date. The results of these experiments highlighted the necessity of accounting for temporal dynamics when interpreting crop water use in response to soil drying, particularly when comparing genotypes with differing OP.}, number={2}, journal={CROP SCIENCE}, author={Beseli, Amber L. and Shekoofa, Avat and Ali, Mujahid and Sinclair, Thomas R.}, year={2020}, pages={945–953} }

In field, these lines differed in soil water extraction depth and in plant wilting. It was hypothesized that HOA in leaves was also expressed in the root tips, and consequently it results in greater root extension and extraction of deeper soil water. Experiments reported here were undertaken in 1-m tall pots in a growth chamber and in the field to test these hypotheses. Periodic harvests of the soil columns during dry-down experiments showed no leaf OA in the two maize lines although the HOA line consistently had a lower leaf osmotic potential than the LOA line by 0.23 MPa. On the other hand, under the slow development of water deficit there was equivalent root tip OA in both lines. Consistent with this equivalency in root tip OA, no consistent difference in root length was observed in any of the experiments. Hence, the basis for the difference in wilting and water use between the two maize lines was not explained by differences in root OA and root extension.}, number={4}, journal={JOURNAL OF CROP IMPROVEMENT}, author={Beseli, Amber and Hall, Antonio J. and Manandhar, Anju and Sinclair, Thomas R.}, year={2019}, month={Jul}, pages={429–444} }
